I am trying to integrate Vuelink 20.0 with UCM 11.1.1.4.0, when I am trying to view some document in Autovue, only for the first time its happening, if I tried again with out closing the browser, it is asking for login credentials, and even after giving the correct credentials, it stays in the same page. After closing the popup window, for any further actions, its redirecting to login page.

If I close the brower and try the same steps in a new browser, then the same thing is repeating(Only for the first time document is opening in AutoVue)
